Include Rust file into procedural call site

help
1

I've implemented a crate for defining several related structures all inside a procedural macro.

I'd find it useful to support something like:

smodel! {
    type Arena = Arena;

    include!("foo.rs");

    include!("bar.rs");

    include!("qux.rs");
}

I'd manually parse these include!(...); calls and expand them to what I expect. Is this somehow possible?

I'm also afraid that the IDE would only discover the file if there is a built-in mechanism for properly including the Rust file in proc_macro.

Can't you just emit those include!()s in the generated code?

Anyway, you can get the current file path with the experimental span API, and then you can access the file and read it.

The problem is that I need to parse the include!() contents for processing purposes.

I also need to get rustc compilation errors in the include!()d file as if it were part of the Rust source tree.

Someone already proposed it though:
